Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes
Advanced Synthesis &Catalysis, EarlyView.The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.

Asymmetric Synthesis of Atropisomeric Amines via Transaminase‐Catalyzed Dynamic Kinetic Resolution
Advanced Synthesis &Catalysis, EarlyView.A dynamic kinetic resolution approach is developed for the atroposelective synthesis of heterobiaryl primary amines. Using transaminases and leveraging Lewis acid‐base interactions to induce racemization, a variety of axially chiral primary amines are produced in high yields and enantioselectivities.

Ni Single Atoms in Zeolite Beta for Selective Alkyne Hydrogenation
Advanced Sustainable Systems, EarlyView.Single‐atom Ni in zeolite Beta (Ni1/BEA) selectively remove trace acetylene from ethylene. Ni1/BEA achieve full conversion with ≈89% ethylene selectivity, stable for 24 h without coking, and 12 times higher TOF than prior zeolite‐supported single‐atom Ni catalysts. Na+ exchange suppress Brønsted acid‐catalyzed oligomerization. Under ethylene‐rich feeds,

Advanced Sustainable Systems, EarlyView.A microwave‐assisted approach yields Zr‐MOF/Ag4P2O7 heterostructures with superior solar responsiveness and efficient charge‐carrier separation. The hybrid photocatalyst rapidly degrades dyes and fluoroquinolone antibiotics into less toxic species under visible‐light. Comprehensive optical, mechanistic, and phytotoxicity analyses reveal its robustness,
